I know this is heretical, but I'm looking for a synthetic stock for my 686 Black Onyx Waterfowler with 3.5" chambers. Wood on the gun now is typical Beretta 2x4 quality, but it's in perfect condition. I'm planning to hunt the gun hard for the next few seasons and would like to put an inexpensive black composite stock on it. Problem is, I have never seen one of these stocks. Anybody know if they even exist, and where I might buy one? Thanks.
